I have been toying with the thought of whether some of the full-bore slugs I have which include a 660gr .735" Lyman Sabot design, a Dixie-inspired design which will cast a .737" slug three weights, an 800gr extra-large HP, an 850gr semi-HP and finally a 910gr solid, also there's a CBE Paradox mold which throws a .735" slug in a 680gr HP and a 750gr solid. I do have a slug sizing setup and have successfully regulated two 12ga paradox guns, one a William Evans Ball & Shot and the other a Westley Richards Explora in the recent past, and loaded up a bunch of ammo in paper cases for these two guns. My concern pertaining to the Carlson's 1-35" twist rifled choke tube that a buddy of mine has on his Winchester, is only with regard to the tubes wall thickness from a safety perspective and whether the torque generated by the FB slugs will lock the choke up in the barrel, whether the slugs will shoot well through the faster twist would remain to be seen, has anyone here tried FB slugs with their rifled choke? Your input would be greatly appreciated.
